KNX ADDRESSING
The
APP
MODULE addressing concept is based on the group addressing of the KNX system. Sending
EnOcean Telegrams as well as transmitting received telegrams is performed based on KNX group
addresses only. The KNX group address is a 16-bit address which is split in a so-called 'real' and a 'virtual'
section. Additionally, there is a 2-digit as well as a 3-digit representation:
3-digit:
MG= Main Group / CG= Central Group / SG= Subgroup
MG / CG / SG
2-digit:
MG= Main Group / SG= Subgroup
MG / SG
Note: The
APP
MODULE interface only supports the 3-digit representation.
Real / Virtual Address Space
The KNX address space ranges in total from 0/0/0 to 31/7/255 (in the 3-digit representation). Therein,
the range from 15/7/255 is designated as real address space and the address space from 16/0/0 to
31/7/255 as virtual address space.
Note: For the communication between EnOcean and KNXnet/IP Routing, only the real address space is
used.
